Code for Thought

English Edition: how are real numbers e.g. 0.1 represented on computers? What can go wrong with using their representation in calculations? And does it matter? These and other questions are the subject of this ByteSized episode with my guests Prof. Ulrich Ruede (University of Erlangen-Nuernberg), Andreas Herten and Edoardo di Napoli (both Research Centre Juelich). Links:https://www.h-schmidt.net/FloatConverter/IEEE754.html  an online tool to convert numbers into their bit/hex equivalent - also showing the rounding errorshttps://dl.acm.org/doi/10.1145/103162.103163  Goldberg Paper: What every computer scientist should know about floating pointshttps://arxiv.org/abs/2012.02492 revisiting Goldberg, Vincent Lafagehttps://en.wikipedia.org/wiki/IEEE_754 the Wiki entry on the IEEE 754 standard for floating points (the standard itself is not accessible for free)https://en.wikipedia.org/wiki/Unit_in_the_last_place definition von "ulp"https://developer.nvidia.com/blog/floating-point-8-an-introduction-to-efficient-lower-precision-ai-training/ NVidia’s take on lower precision numbers https://indico.esa.int/event/445/contributions/8473/attachments/5559/9378/gernigon_cedric_EDHPC2023.pdf list of lower precision formatshttps://en.wikipedia.org/wiki/Chinese_remainder_theorem Chinese remainder theoremI would like to thank the STEP-UP project in the UK for supporting this series of ByteSized episodes. Get in touchThank you for listening!

English Edition: NextBrain is a next generation atlas of the human brain. Juan Eugenio Iglesias Gonzales from Massachusetts General in Boston, US, has been leading this project. My colleague James Hughes (University College London) and I were working on part of it at the time. And in this episode we explore, once again, what NextBrain is, how it evolved using AI tools in a shifting technology landscape and how it can be used in education and research. Linkshttps://www.nature.com/articles/s41586-025-09708-2  the published paperhttps://github-pages.ucl.ac.uk/NextBrain/#/home  the UCL project for the browserhttps://github.com/UCL/NextBrain#  the NextBrain projecthttps://lemon.martinos.org/  Eugenio's research home pagehttps://www.fil.ion.ucl.ac.uk/spm/  https://freesurfer.net/ https://github.com/freesurfer/freesurfer  Get in touchThank you for listening!

English Edition: with my guests Bernd Ulmann and Daniel Thuerck I am looking at the fascinating world of analog computers. Far from being "yesterday's" machines, there is a lot of interest in building analog devices. So what are they, what are they used for, and how do you work with them. Links:https://anabrid.com/ https://the-analog-thing.org https://anabrid.com/redachttps://shop.anabrid.com/collections/lucidac https://www.analogmuseum.org/english/ https://www.oreilly.com/library/view/analog-and-hybrid/9783110787887/  Bernd Ulmann's bookhttps://analog-computing-days.org/  The Analog Computing Days conference in Frankfurt am Main, Germany 11/12 June 2026https://collection.sciencemuseumgroup.org.uk/objects/co64127/phillips-economic-computer  The Phillips MONIAC analog computer at the Science Museum in London https://en.wikipedia.org/wiki/Phillips_Machine https://www.econ.cam.ac.uk/news/2022/trickle-down-economics-phillips-machine-shows-how-macroeconomy-flows https://www.sciencemuseum.org.uk/objects-and-stories/charles-babbages-difference-engines-and-science-museum Part of the Difference Engine by C Babbagehttps://en.wikipedia.org/wiki/Slide_rule a simple "analog computer"  https://research.ibm.com/projects/analog-ai https://en.wikipedia.org/wiki/Analog_computer https://research.ibm.com/projects/analog-ai Research into analog computers at IBMGet in touchThank you for listening!

English Edition: making software, digital data and other artefacts count in research evaluations has always been a challenge. But there are plenty of people and initiatives like the https://hidden-ref.org in the UK who want to change research culture. And I talked to three people who are working in this field to find out what the challenges are and what they do to make software and digital technologies count (more): Simon Hettrick (Uni Southampton), Jack Atkinson (Uni Cambridge) and Will Swansborough-Aston (Uni Exeter).Links:https://hidden-ref.org/ The Hidden REF https://feeds.acast.com/public/shows/what-the-ref  What the REF podcasthttps://2029.ref.ac.uk/  The Research Excellent Framework for 2029https://joss.theoj.org/  The Journal of Open Source Softwarehttps://data.agu.org/notebooks-now/ Notebooks Nowhttps://mystmd.org/guide/quickstart-jupyter-lab-myst  Myst markup language in Jupyter https://orkg.org/ Open Research Knowledge Graph Get in touchThank you for listening!

Deutsche Ausgabe: Anfang September 2025 wurde der neue Hochleistungsrechner Jupiter in Betrieb genommen, mit viel Fanfaren und Prominenz. Zurecht, denn Jupiter ist der schnellste Rechner in Europa. Aber wie kriegt man so eine Maschine am Laufen? Und wie kann man sie instand halten. Das habe ich mit meinen Gästen Andreas Herten und Benedikt von St Vieth vom Forschungszentrum Jülich diskutiert. Das ist die letzte Folge der 10. Serie von Code for Thought. Und es geht am 3. Februar 2026 wieder mit der 11. Serie weiter (einschließlich deutschsprachiger Folgen). Alles Gute für die Feiertage und 2026! Get in touchThank you for listening! Merci de votre écoute!
